Please which of these would benefit most from overwintering in a heated greenhouse? A local greenhouse is offering to do it for those that have more exotic plants.

Medinilla magnifica
Just found this: "
A: After a Medinilla has finished flowering and the old flowers have fallen off or have been removed, the plant will grow new shoots. In this period, the plant can be given some plant feed once every two weeks. When the new shoots are approx. 10 inches long, you have to place the plant in a cooler environment at 17-18C (63 64F) still with high light in winter, diffused light in summer. When after approx. 10 weeks, the flower buds are about 1 inch; you can place it in a warmer room." I'm thinking it will do fine in our house.



Hawaii'an Sunset Vine
Blue Butterfly Bush Clerodendrum Ugandense
iochroma
Plumeria (Dwarf)...I know I could let it go dormant.
Lady Margaret Passiflora
Brugmansia (still haven't Y'ed yet)
Taro...can I dig up and put in smaller pot?
Elephant Ears...can I dig up and put in smaller pot?
Banana...can I dig up and put in smaller pot?
Hibiscus
Mandevilla
Duranta
Oleander

Thank you ever so much for your input!

ALL of these will continue to grow and bloom in a heated greenhouse, but go dormant/die if the temp. falls below 40 degrees. I grow all of these in my zone 8b, and they go dormant when the temps. drop below 40 for several hours.

You can put both the Taro, EE's and Bananas in pots for the winter. You can let the Plumeria go dormant - just shake off the soil and put it in the closet.

:D :D :D :D :D

Thank you ever so much Homer and Kay!!! I was wondering if any of the above needed dormancy (or if it would hurt them) and now you've answered that ? :o)

Homer I do indeed realize how spoiled those of us that were offered this awesome gift are! In fact my jaw dropped when it was mentioned to me.

I didn't want to waste any of her space if they couldn't handle the conditions there but now I feel much better. I will have to start potting some of the plants into smaller pots now (some are in huge heavy clay pots...they are about 4 feet tall now re elephant ears and taro's etc.

I don't think EE's (taros) *need* dormancy but putting large plants in small pots and expecting them to stay robust will be difficult if at all possible. Personally, I would just let them and the bananas go dormant, keep them dry and above freezing, and use the GH for shrub type plants like the hibiscus, oleander, mandevilla, brugmansias and the various vines.

You might consider using the GH to jump start the big bulbous plants in the spring. By starting them sooner, in a warm sunny environment, you should have full plants ready to go out in your garden as soon as the weather cooperates. You can then use the smaller pots to get them going then move them into the larger pots when they are outside and need more room for their roots.

Thank you for your input as well Ardesia :D...I'll be making some decisions very soon as to what goes where. A couple of the Taro's I may hunt down a lighter larger pot for them and others I'll let go into dormancy. They are looking so fine right now and very eye-catching.

This time of year is such a heartbreaker up here ... our season is so short and plants are just now becoming breathtaking (oh what a couple more months of growing weather would do)!

*sigh*

Strange isn't it? Our season is so long some plants start looking raggedy by this time of year from the heat.

That GH will give you lots of options for your tropicals. Next year they will be ready and rarin' to go when summer arrives in SK.
