We have a wonderful selection of bulbs and other special plants that take certain care and attention. On this page you will find the various instructions on caring for your special plants.

Most of our bulbs are available only from January through June. You can find which bulbs we have included in the list of plants on the, “Current Native Plant Inventory,” tab listed on this website.

  • Bulbs in the nursery are found in orange pots only.
  • Most bulbs should not be divided or planted out until dormant. Keep them in their pots until all foliage has completely died back.
  • Water sparingly, once a week is generally sufficient.  Stop watering when they start blooming or the leaves are starting to die back.
  • Sift/dig up/separate bulbs when completely dormant. Store in cool, dry, well ventilated  place and re-plant before rains start, around September /October.
  • Very small bulbs can be re-planted in the same pot to let grow up for another year. Top with a pinch of bulb fertilizer.
  • Exceptions: Toxicoscordion and Chlorogalum  have more robust root systems and can be carefully divided any time.
  • All our bulbs are Summer dormant and should not receive any Summer water.
  • Bulbs planted in the ground do not need supplemental water unless there is  severe drought, or any additional  fertilizer.
  • Calochortus sp. are especially susceptible to rot.
  • Bulbs may need protection from gophers (underground wire cages), mice, squirrels, other rodents and some birds (above ground cages), snails and slugs (copper strips, oyster shells, Sluggo™ type bait)
  • Toxicoscordion bulbs are toxic to most critters, but snails and slugs love the foliage.
  • Bulbs require good drainage – amend soil (perlite, expanded shale etc), plant on slope or raised bed/mound
  • For easier protection from pests, good drainage and water control it may be best to grow bulbs in containers. Containers  should be at least 10 – 12″ deep. Commercial potting mix (not soil) works well as growing medium, preferably without added fertilizer (too much nitrogen). A small amount of bulb fertilizer (generous pinch) should be added once a year to each pot.
  • Our homemade bulb mix: 2 parts perlite, 2 parts vermiculite, 1 part peat (cocoa peat or coir is OK), 1 part sand. Add a pinch (1/4 tsp) of bulb fertilizer per 1 gal pot.
