Graduate student Lauren “Ivy” Clark has been knee deep in seeds ever since
she started her Master’s work at University of Washington. She first came to work with Rare Care in 2009 to develop protocols for propagating ten shrub-steppe species from seed for a project Rare Care was working on with BLM. Having developed an interest in germination ecology, Ivy also started working with Rare Care’s rare plant seed collection, conducting germination tests on collections held in the Miller Seed Vault. This ongoing work dovetails nicely with her thesis work, in which she explores the potential for hybridization between golden paintbrush (Castilleja levisecta) and harsh Indian paintbrush (C. hispida).
Both Castilleja species occur on Puget Sound prairies, and hybridization has been observed in a nursery setting. Recent golden paintbrush reintroductions have resulted in both species growing in close proximity to one another at out-planting sites. After ascertaining that the same pollinator species frequent both species, Ivy collected seeds from both species where they co-occur and is propagating them in the greenhouse. She will evaluate morphological features of the progeny to determine whether and to what extent hybridization is occurring at these reintroduction sites and whether the risk of hybridization is reduced by increasing the distance between neighboring individuals of the two species.
Ivy has had an interest in plants for as long as she can remember. Growing up in Texas, her interest in the natural world was nurtured by her parents. She’s held a variety of jobs since becoming a biologist, many of them restricting her to laboratories. Finding that she really enjoys being in the field, she hopes to use her skills and degree to work in the restoration ecology field. In the meantime, we are delighted to have her working on Rare Care projects and caring for our ex situ collection.

I had so much fun participating in the Fiddleheads Program these past couple of months. Through out the sessions we play games, explore, do arts and crafts, and teach the kids about their surroundings. What is special about this program is the kids get to interact with the nature they are learning about directly instead of reading it from a textbook or in a classroom.
On our first walk through the Arboretum we taught the kids about fall and how the environment changes during that time period. We explored how the leaves change colors and how the leaves eventually fall off the trees. The kids were able to see the changes happening with their own eyes. Through out the walk we gave them each a brown bag and they were to fill it with the leaves that fell off the trees. At the end of the walk we reminded them why they fell off the trees and had them each do a leaf rubbing so they could take it home and have it be a reminder of what happens during fall. All through out the walk the kids were asking questions, interacting with nature, feeling the leaves, and touching the trees.
One of my favorite games we played with the kids was called the color game. Sarah and I each gave the kids a paint swatch and they were to find a plant, animal or anything in nature that was the same color. This was a unique and fun way to get the kids to explore nature. The kids were running all around and would show us what they found that matched their paint swatch. If they didn’t know what the species or plant was we would tell them and have them share it with the other kids so they could all learn about each others.
Another game the kids loved was called the matching game. Sarah and I laid out a bunch of leaves two of each kind and had the kids play a matching game and at the end we would have them guess what the name of the leaf was. Then we would circle as a group and talk about each leaf and point out what the tree looked like that the leaf came from. In that kind of setting the kids are able to learn about the environment in a fun and stress free environment. They retain the information better and see how humans and other species directly impact the environment. Each session has an overall theme so the kids are constantly learning about different issues and topics related to nature.

Join us Saturday, December 15 from 10:30 to 11:15 am for stories and art.
In the Pacific Northwest, we treasure our evergreen forests, and today’s stories celebrate them. After the stories you’ll have time to color a tree picture or use homemade salt dough to sculpt your own evergreen tree. Free for kids ages 3 to 8 and their parents.

Miller Library monthly Story Program happens once a month in the Children’s Corner.

This holiday season, we’re taking you indoors into our Douglas Conservatory and showcasing a plant to warm up our botanical curiosities. This unique and elegant flowering maple (though not technically a maple (that’s the genus Acer)) is best known as an annual shrub for containers and summer bedding, but I haven’t the heart to just chuck it into the compost. So we brought it in for the winter and given a little care, it has decided to flower for us.
Flowering maples come in an assortment of colors and have the distinct maple-like foliage that gives it its common name. They benefit from full sun/part shade and regular watering and fertilizing during the growing season. They seem to bloom on and off and gentle pruning keeps plants bushy and loaded with flowers. ‘Tiger Eyes’ isn’t as prolific a bloomer and stands taller and lankier than most other Flowering maples, but its flowers are too exquisite and makes up for it.
Common Name: Flowering Maple
Location: Douglas Conservatory
Exposure: Full Sun/Part Shade
Height and spread: 6-8ft. tall x 3ft. wide
Bloom Time: Sporadically throughout the year. Heaviest in summer

1) Abies alba ‘Hybrid’ (Silver Fir)
- Silver Fir is the species first used as a Christmas tree.
- A resinous essential oil can be extracted. The pine-scented oil has soothing qualities and is used in perfumes and bath products.
- This magnificent specimen can be found on Arboretum Drive.
2) Cornus sericea ‘Cardinal’ (Red Osier Dogwood)
- Bright red twigs provide winter interest in the garden and a beautiful accent to holiday decorations.
- There are many benefits to Red Osier Dogwood, including overall hardiness and wildlife habitat.
- Native to the Pacific Northwest, this cultivar can be found in the Pacific Connections Entry Garden.
3) Ilex opaca ‘Emily’ (Emily American Holly)
- Holly is a popular winter, Christmas and holiday season decoration.
- In English poetry, holly is inseparably connected with merry-making.
- American Holly is the perfect substitute for English Holly because it is not invasive.
- Several cultivars of Ilex opaca can be found in the island beds of the Pacific Connections Garden.
4) Picea brachytyla (Sargent Spruce)
- Many species of spruce are used as Christmas trees.
- Spruce are important economically for timber, resin and Christmas tree production.
- The Sargent Spruce is native to China and is threatened by habitat loss.
5) Thuja plicata (Western Red Cedar)
- The flattened sprays of dark green foliage droop gracefully and are prefect for holiday wreaths and swags.
- Strongly aromatic, the scent of crushed Western Red Cedar is reminiscent of pineapple.
- A strong player in our native matrix, beautiful Thuja plicata can be found throughout the entire Arboretum.
