Ah, yes, the nasties you planted are a vining/sprawling variety. Some do that and some stay in neat little clumps. To protect the bougie, just re-direct the long stems away, or under it's branches. Or snip them off and they'll branch. OR just pinch off any leaves that shade the bougie. The leaves will last a week in a flower vase, and the nasturtium flowers are nice as cut flowers, too. They're also edible, btw. A sort of a sweet, spicy flavor that's nice in salads.The nasties will not twine or climb, but they may get big leaves that will hog all the sunlight, which would set the little bougie back.
A handful of slow-release fert should keep everybody happy in there until you're ready to remove the nasties (most likely May or June) and you can give the bougie another bit of fert then to carry it over the summer. It will most likely take off through the summer weather. They like the heat and humidity.
I am surrendering and admitting it is spring already. Hauled out my bag of Osmocote and am touring the yard this week giving everybody a light dose. I'll do the same again at the end of May and that's all my garden gets (except the veggies, of course). When you're spreading granular fert, don't forget that the plant's roots go out a little further than the spread of the branches, as a rule. So don't put all the fert in by the stem of the plant.
With the oak trees dropping leaves and putting out blooms this week, it really feels like mid-March! That's when we usually have to clean out the gutters after the oaks finish dropping all the leaves, and blossoms. To be honest, if we did get one more cold night while the oaks have flowers going, it wouldn't break my heart. Actually might cut the annual agony short by zapping the flowers so they didn't make pollen. Wouldn't that be worth the little headache of covering the tender plants! (I can dream . . )
Yeah, HD and Lowe's continue to sell tomato starts right into summer, only because I'm sure their suppliers up north send them - not realizing that in Florida tomatoes just do not survive the summer heat. They really should send them back, come May or so. Some peppers will struggle through, and eggplants don't mind the heat.
Basil is a great herb that goes through summer, and there sure are some pretty ones available - have you seen 'Pesto Perpetuo'? It has dark stems and lovely variegated leaves - white, light green and dark green. Tastes wonderful, and I get it at HD. Last year I grew one called 'Cardinal' that had huge red flower heads well into summer, although I had to order seeds for that one. Thai basil has little purple & white flowers all the time.
Keep in mind the idea that you will succeed if you can get "The Right Plant in the Right Place" most of the time. For example, rolling back to our original discussion about your C.Pulch plants, you know you're pushing the climate envelope a bit on those, but to be honest, it's MUCH easier to succeed with a tropical plant that loves the heat, and you have to protect from the cold than trying to grow temperate plants that will struggle with the heat. The cold weather is usually spotty and transient, but you can depend upon months of hot, humid weather every year. It's discouraging to a novice gardener to nurture plants and then have them fail. What you have to tell yourself when something dies is "well, that plant sure wasn't in the right place" and don't try that plant there next time. Give it more shade, or more sun, or less water or . . . like the lobelias and sweet peas, start the seeds in October not January.
I'm hoping to steer your sights more towards things that are likely to succeed, to make a basis for your garden. You have a lot better chance of keeping the C.pulch's going for years than you have of making those baby lobelias survive through June, let alone bloom and be beautiful. Go get some already in bloom at Lowe's, and enjoy them until they poop out. Get some plumbagos if you want a nice blue background shrub. They're dirt dependable and bloom 9 or 10 months of the year. Pentas are a lovely, dependable summer flower that comes in some nice reds that would accent your C.pulch shrubs, and both large 3ft. and dwarf 1ft. varieties.
Back to the gladiola discussion, trust me, I love them too. My mother grew them faithfully up in Canada, and I grew them for sentimental reasons every year in Salt Lake City. Luckily for me, I still have a garden in SLC at my daughter's place. But honestly, now that you live here let somebody else grow them for you! Although I almost never buy cut flowers I do buy glads at Publix for $4.99 for a bouquet that lasts in the house for a week or 10 days. Yes, the cut flowers just coming into bloom cost less than buying bulbs! If you plant them as bulbs, you'll nurture them for 3 months, and I'd be willing to bet the flowers wouldn't last 4 days outside in late April to May heat. Then the foliage gets attacked by thrips and looks awful for the rest of the summer, standing there taunting you every time you see them. If the bugs get to the foliage before they're ready to flower, then they won't flower at all. Don't set yourself up for failure, there!
Speaking from long, hard experience at murdering thousands of plants that I couldn't find the right place for, here. That's the real reason they call us Master Gardeners - we persist even though we kill so many plants . . . LoL. On the up side, every failure is a learning experience.
