teeka you can get this consultation for free. In Florida the utilities companies do a free energy audit and advise on insulation. You can often get a rebate for installing insulation. Your water company will also advise on rain barrels - our local company sells wonderful rain barrels at a very low price. About pavers - the term to use is "permeable surface". Your building department can give you ideas on what materials qualify, and how to calculate your "square foot" needs. Then price your choice of materials, plus installation. Your building code allows so much of a percentage of your property to have "impermeable" covering (slab and driveway/sidewalk) Switching to permeable driveway can actually allow you to add on to your house....

my first thought was campanula punctata, but that would have white roots that go down a ways and then tubers under that; then more roots going down under those - like that pesky orange alstroemeria! both are horrible weeds, IMO. are you digging or pulling when you weed it out? how far down do the roots go? (ie can you get the entire root when you dig?) do you notice if it is lessening when you weed it each year? does it bloom? when? does it grow tall? what is the flower color and form? you say it has long white roots - i'm wondering if the roots are tap roots, like a dandelion, or runner roots like a Canada thistle's - they go down a ways, then interconnect across and underground; hard to eradicate that kind of weed. just keep the tops pulled - ie don't let it photosynthesize and eventually you will tire it out. by all means keep it from going to seed. look around and see if you can find a "parent plant" that looks like it. that may be your culprit going to seed. this is a good photo. if you have a county extension agent, noxious weed board, or even master gardeners that do plant ID, start with them. i'd start with the extension agent first.

Not C persicifolia. Flowers are not the right shape. There are loads of possibilities since we can't see the height, the habit or the foliage. C latifolia would be one. C trachelium would be another. Be aware that even if these were harvested by the seller from white flowered plants there is no guarantee that all the progeny will have white flowers. You may well end up with a good number of blue flowered plants. There are literally hundreds of species of Campanula, not to mention all the hybrids and cultivars. So when buying seed in future it would be wise to get the full botanical name so you know what you are getting.

. It looks like Prunella vulgaris, Self Heal. But if that is a pink flower near the bottom of the lowest branch it is not that. Or is that just a blossom from something else?
