Gardeners' Notes:


On Apr 5, 2015, azurescens from South Bend, WA (Zone 8b) wrote:

These bulbs are hardier than assumed, at least to Sunset Zones 5 and 6, or USDA 8a. A plant in a south Portland, Oregon neighborhood has thrived for years outdoors in a rocky, well drained bed. Another plant on the Washington coast has endured wet winters and temps into the low 20s without a care. Give it as much sun as possible up north and skip the summer water if you can. Worth experimenting with if you live outside of the southern sun belts and have zonal denial.

I puchased 2, 3 years ago they bloomed well the first year and the second but lesser the second, the third year they didn't bloom at all and I think I may have lost one altogether for no apparent reason this year, they are both treated the same, in the same type containers, same water, in the same area and exposure. One seems to be coming up OK with leaves the other I haven't seen a peep of, as yet not sure all Cali plants are real happy with Fla weather conditions, heat? Humidity? Rain? Altitude? What ever it is they are not blooming here...I sure hope I see the hide of the other one there not cheap and I'm not going to spring for another one!

So far I am satisfied with this. Leaves are finally showing up and looking thick!

It fits well with my drought tolerant garden.

Until a full year passes, I will come back for more comments on this exciting exotic plant!

I received the bulb, planted the bulb and let the top part of it stick out of the ground. Watered after planting and left it alone. I made sure it was planted in an area where water will not sit!

UPDATE: I planted in 2010 and its 2011, I have a wonderful bloom stalk! =)

We moved from Southern California to Southern NM and I dug these two bulbs up, potted them up and one bloomed last year during the Move in Oct/Nov 2006, the 2nd one bloomed this summer in 2007. In August 2007, they were both put into the ground with no leaves, a month later, now they are both sending up the green leaves and I ordered 5 more bulbs that arrived yesterday and were put in the ground yesterday 9-26-07. Everything says that they should be able to take a frost, and the ground doesn't freeze here, so I'll up date come next year after we see what happens to them.

So far, two years experience in western Michigan. Full southern exposure. It appears dormant during the hot summer, then in early Fall, it awakens and begins to produce foliage. The bulbs are large, but even at 6-7 inches in diameter, may be too small to produce the tall flower stalk. Once the temperatures begin threaten with frost, I've been able to bring the plant indoors and set it next to a sunny window and have it continue to grow through February before the foliage begins to fail. Other than the Winter indoors, it spends its time outdoors in a large pot (3x the width and depth of the bulb).

large bulb native to Malta and surrounding islands. Leaves erupt in the fall and dry up in the spring to early summer. Then a flower stalk shoots out in late summer up to 3' tall, sometimes taller. Single raceme covered with white, shiny flowers. Very drought tolerant. Toxic plant, used extensive in medicine as a source of a variety of compounds.
