Hellebore is a great water-wise choice for hard-to-plant spot: dry shade

This “rose” blooms where (and when) others won’t. It flowers in dry shade – in late winter.
On March 2, the first day of Lent, my Lenten roses were in full flower. In shades from near black to creamy pale green, those interesting blooms actually arrived way early; they’ve been opening for most of February. But they’re so long lasting, they’ll still be around for Easter.
“Lenten rose” is the nickname for hellebore, a wonderful shade-loving perennial. Despite the nickname, they’re only a distant relative of roses. They’re actually close cousins to ranunculus.
Native to Southeastern Europe, hellebores are well adapted to our Mediterranean climate. Once established, they can get by with only twice-monthly irrigation, which makes them a great pick for water-wise landscapes.
Naturally compact, they love dry filtered shade, such as under trees. Hellebores can tolerate some sun, too; just not full Sacramento summer sun.
Their large, leathery leaves stay close to the ground, usually under 1 foot tall. In winter, they send up flower stalks with large bell-like blooms.
These plants are extremely low maintenance. Unlike roses, Lenten roses need no pruning. Just snip off any unattractive leaves in summer.
Another plus for hellebores: Deer don’t like them. Hellebores also can tolerate colder temperatures, making them ideal for foothill gardens.
New hybrids have expanded the range of hellebore colors and petal patterns, from pure white to darkest purple black. Most varieties fade to shades of pink or purple.
Two hybrid hellebores have been featured by the UC Davis Arboretum as part of its water-wise plant collections: Pink Frost ( Helleborus X ballardiae ‘Coseh 710’ ) and Mahogany Snow ( Helleborus X ballardiae ‘Coseh 930’ ).
Pink Frost has striking cream-colored flowers with pretty pink edges that last for weeks in the garden. Mahogany Snow is similar with creamy petals reversed with dark pink. Those varieties and others can be seen in the arboretum’s Terrace Garden and Ruth Risdon Storer Garden.
Corsican hellebores, which have bright green flowers, are featured in the Arboretum’s White Flower Garden near the gazebo.

Dig In: Garden checklist for week of Sept. 25
This week's warm break will revive summer crops such as peppers and tomatoes that may still be trying to produce fruit. Pumpkins and winter squash will add weight rapidly.
Be on the lookout for powdery mildew and other fungal diseases that may be enjoying this combination of warm air and moist soil.
* Late September is ideal for sowing a new lawn or re-seeding bare spots.
* Compost annuals and vegetable crops that have finished producing.
* Cultivate and add compost to the soil to replenish its nutrients for fall and winter vegetables and flowers.
* Plant for fall now. The warm soil will get cool-season veggies and flowers off to a fast start.
* Plant onions, lettuce, peas, radishes, turnips, beets, carrots, bok choy, spinach and potatoes directly into the vegetable beds.
* Transplant lettuce, cabbage, broccoli, kale, Brussels sprouts and cauliflower.
* Sow seeds of California poppies, clarkia and African daisies.
* Transplant cool-weather annuals such as pansies, violas, fairy primroses, calendulas, stocks and snapdragons.
* Divide and replant bulbs, rhizomes and perennials.
* Dig up and divide daylilies as they complete their bloom cycle.
* Divide and transplant peonies that have become overcrowded. Replant with "eyes" about an inch below the soil surface.
