Product Details

Product Details

Vigorous and easy to please, Oenothera speciosa 'Siskiyou' (Evening Primrose) makes a ground cover of dense, weed-smothering mats. The dark-veined, rose-pink flowers shade to white in the center and feature a greenish yellow throat. They are showiest in late spring and summer, but plants will rebloom if cut back as the flowers fade. Discovered at Oregon's legendary Siskiyou Rare Plant Nursery.

Oenothera is a genus of more than 200 species from the Western Hemisphere. All have large, open flowers and a number are fine ornamental plants. Oenothera like sun, well-drained soil and are drought tolerant.

The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.


We ship our bulbs and plants at the right time for planting in your area, except as noted, with orders dispatched on a first-come, first-served basis by climate zone. We also ship a wide range of containers and planters, tools, supplies, fertilizers, garden wear, garden decor items, as well as indoor decorations like wreaths and dried bouquets when available. Estimated dates for shipping are indicated in the green Shipping Details box for each item. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at the expected time of delivery.


We guarantee to ship plants that are in prime condition for growing. If your order is damaged or fails to meet your expectations, we will cheerfully replace or refund it. Please contact our Customer Service Department at 1-800-503-9624 or email us at [email protected]. Please include your order number or customer number when contacting us.

Hardy and Pretty

I have these in the front of a little three tiered section of my garden, with foxgloves in the middle and hollyhocks in back. I planted them at the end of March. It is now mid-May and they already are flowering. For such a small plant they have surprisingly large flowers. I saw this plant at a local nursery, and the stems were stringy. The WFF plants have a nice shape and are not stringy at all.

Latin Name Pronunciation: ee-noth'e-ra  

Oenothera thrives in full sun (or partial shade in the South) and well-drained soil. Tolerates drought and poor soil.

O. speciosa varieties spread vigorously from running roots. Plant where there is room to roam, or where a wall or the lawn mower limits progress. In a border, plant in a plastic tub sunk in the soil almost to the lip. Cut holes in the bottom of the tub for drainage.
