Frozen, Part 3

All good things must come to an end, especially when they are not in your hardiness zone.  This final installment documents some of the more miserable-looking plants after a week of subfreezing temps with lows reaching down to 10 degrees F (-12C).

Just melt already!!!
Once again, the survival scale:

1 = Dead
2 = Severely damaged and may never fully recover
3 = Severely damaged but will probably fully recover eventually
4 = Severely damaged but will probably fully recover in less than a year
5 = Moderate cosmetic (e.g. leaf) damage but no known structural damage
6 = Minor leaf/flower damage
7 = No damage

Melianthus major (Honey bush) = 4 (But it will quickly regrow from the roots in the spring)
Hebe x andersonii 'Variegata' = 1 or 2 (It's not good when leaves turn lighter or darker after a frost - this plant did both)
Lavatera × clementii 'Rosea' (Tree mallow) = 5 (Normally evergreen.  Oh well)
Acanthus mollis (Bear's breeches) = 4 (Maybe the seaweed look will catch on)
Francoa sonchifolia = 5 (Normally this is perfectly and unsuspectingly evergreen)
Rubus lineatus = 5 (The leaves are dead but the stems seem to be undamaged)
Stauntonia leucantha = 7
Bignonia capreolata 'Tangerine Beauty' = 7 (Still fully evergreen...the tag says it can be semi-evergreen & hardy to -10F)
Musa basjoo (Hardy banana) = 3 (They have been frozen back too far to reach their max height this year)
Holboellia coriacea 'Cathedral Gem' = 6 (Bronzed foliage, otherwise looks ok)
Ceanothus 'Tuxedo' = 5 (Larger leaves were dessicated but smaller leaves look ok)
Cordyline australias = 1 or 2 (Dead or mostly dead)
Citrus ichangensis x C. reticulata = 7 (Leaves curled a little during the frost, but now looks perfectly happy)
Daphne bhoula = 3 (Time will reaveal how badly damaged it is)
And finally...

Pachyphytum hookeri = ??
So far this pachyphytum is still alive - much to the amazement of the neighbors walking by (and me).  It is in full sun, protected from rain overhead by a tree, and is in very well-draining soil.  I was never really expecting it to survive the entire winter, but if it looks this good after the frost we just had, I'm beginning to think it stands a chance!


  1. Nice surprise with the Pachyphytum bracteosum! My Acanthus mollis look just about like yours, this just seems to mean they come roaring back extra strong in the spring. Do you think the Rubus lineatus will get new foliage along the stems? I assumed I would be cutting them back and it would regrow from the ground. Oh and so far my Cordyline australias are unscathed, I keep expected them to droop or fall over but they look fine...

    1. It's amazing what survives and what doesn't. A passion vine I have growing in large planter is still looking perfectly alive. I didn't even bother protecting it because I assumed it would be toast but it obviously wants to live!

    2. btw...not sure about the rubus lineatus but I'll keep it up until spring just in case :)
