The Q&A Archives: Planting In Full sun

Question: I live in a condo and have a beautiful roof-top patio that is in full sun all day long...what plants can I use that will withstand this scorching location? In past I have used geraniums and marigolds in planter boxes but I would like a change this year. Also - any suggestions for a vine to cover lattice dividers that can withstand full sun all day long? I was thinking of morning glory....nothing ever seems to kill it!

Answer: My gosh, the whole garden world is up for grabs! Are you looking for perennials? You can absolutely grow perennials in containers just don't expect them to overwinter there without some protection. Here are a few full sun selections: Achillea, Aster, Coreopsis, Coneflower, Dianthus, Euphorbia, Delosperma, Erigeron, Geranium, Heliopsis, Lavender, Monarda, Nepeta, Poppy, Rudbeckia, Scabiosa, Stachys, Sedum, Shasta Daisy, etc. Looking for annuals? Try: Abutilon, Calendula, Celosia, Centaurea, Clianthus, Cosmos, Coreopsis, Gazania, Gloriosa Daisy, Bells of Ireland, Nigella, Starflower, Xeranthemum. Your main considerations are choosing adequate containers for your plantings, good soil for them to grow in (enhance your potting mix with some organic matter like compost), fertilizing regularly (follow package application rates), and, last but not least, probably most important in your case...keep on top of watering. Containerized plants dry out quickly anywhere and in the environment you describe they will need watering at least once a day during the hot summer months. For vines, try: Morning Glory, Moonflower, Thunbergia, (all three are annuals).
