Common name - Hens and Chicks / Cobweb

 

Flowering period - Blooms in summer.

 

Features - They are perennial succulent herbs that grow in very tight rosettes. Each rosette may have up to 50-60 leaves. This cultivar reaches up to 2 inches across and clumps can reach several feet across with age. The tips of the leaves are connected with thin cobwebby hairs. A reliable solution for hot, windy locations where nothing else can grow. Trouble-free and long-lived.

 

Spacing - Plant 6" to 12" apart (15 - 30 cm)

 

Height - Grows 2" to 5" tall (5 - 13 cm)

 

Soil and water - Best if planted in gritty, sharply drained soil. Allow soil to dry between thorough waterings.

 

Light requirements - Plant in full sun.

 

Best use - Reliable plants for rock gardens, alpine troughs, patio containers and border edges.

 

Growing tips - Sempervivum species are commonly called "hens and chicks" for their habit of setting small rosette offshoots that surround the larger mother plant. This species sets offshoots that match the size of the mother plant, forming a group of more or less equal sized rosettes.

 

Hardiness - Hardy to USDA zone 5 to 8

 

 

Perennial definition

Perennials - FAQs

Q - When should I cut down my perennial plants?
A - It is often a matter of choice, but the easiest way to know whether to cut down a plant at the end of the season is if it has finished flowering; has browning or dying leaves; is grown leggy or too bushy.

 

Q - How do I know if my garden mums are perennial?
A - Leave them in the ground until the next Spring, and then check for new growth below the crown. If you see new green growth, cut the stems down and plant over until they come back in late summer or early fall.

 

Q - Which perennials tolerate drought?
A - Purple coneflower (or Echinacea) and aster will tolerate drought well.

 

Q - When is the best time to water my plants?
A - Early morning is best, because plants have a chance to soak up the moisture. Watering late in the evening can promote disease in plants.

 

Q - What is the difference between an annual and a perennial?
A - An Annual goes through its life cycle in one summer, a perennial will bloom summer after summer.

 

Q - What is the difference between a biennial and a perennial?
A - A biennial plant is a flowering plant that takes two years to complete its biological lifecycle, a perennial will bloom summer after summer.

 

Q - Should I divide my perennials, how often?
A - Some plants will need to be divided every 3-5 years. If your plant looks crowded and doesn't appear to be blooming as it used to, then it might be time to divide it.

 

Q - Can I grow perennials in containers?
A - Yes you can, and there are many benefits. Although you may not be able to over-winter perennials in containers because they may not tolerate the harder freeze.

 

Q - How much fertilizer should I use to make my flower beds look good?
A - Different plants need different fertilizers, fertilizing once every 2 weeks will promote strong healthy plant growth. Too much fertilizer can be bad.

 

Q - How far apart should I plant my perennials?
A - Consult the plant care tag and consider the height and width of the plant once it reached it's full size.
