Fantastic! Thank you guys....close to a Monstera then, but their labelling could have been somewhat better! I shall try very hard to keep up the good work (although I suspect the plant's success is more down to the plant itself than to anything I'm doing!! - maybe it just likes my windowsill.....) Thanks again - I'm off to read up on it now :-)

The only colorful bulbs are crocuses and a few Siberian squill, no open flowers yet, but you can see the colors in the closed blossoms. The daffodils don't seem to have even emerged yet. There's a pansy or two in bloom. Lots of other stuff going on  corn salad has come back; sorrel, thyme, and sage have leafed out. Brambles have leaf buds, some (blackberries) starting to break. Celeriac and just a couple of kale and chard plants seem to have made it through the winter.

This is a lovely room! In a small space continuity is important. Before you add or paint anything else, paint the daybed and both chairs a dark brown, British Colonial as mentioned above. This way you can add the color you want here and there. The table in front of the daybed needs to be higher, like a tea table height. Use the chest on the side. To make the daybed more comfy, add old fashioned wedge pillows across the back and then the big pillows on top. They are the best support and you won't even see them. https://www.amazon.com/Bolster-Replacement-Insert-Cushion-Perfect/dp/B011CZWYT6/ref=sr_1_3?ie=UTF8&qid=1542001435&sr=8-3&keywords=wedge+daybed+pillow&dpID=41J6VtPqM6L&preST=SY300_QL70&dpSrc=srch

This would be why you 'water' your foundations - pretty much all of Texas has clay soils, high temperatures, and random but alternating periods which vary in length, of drought then more rain than it can handle. Placement of the soaker hose that other posters have mentioned, seems to be a key factor in the success of your foundation watering process. OP, that skinny planter under the overhang and behind the larger one might be something that the builder did to keep roots from whatever is in the bed in front of it from growing and making their way into your crawl space. I can't be entirely sure because I'm not there to look at it in person. :P My parents had a bed planter along both sides of the garage which was on slab only, while the rest of the house had a raised foundation (this was in SoCal) and planters along that in front where the master bed/bath was as well as in the back where the other two bedrooms were. When they decided to extend the master bedroom about 6 feet and reducing the sqft of lawn from where the front of the house ended to the sidewalk, they had to add some additional supports that went down into the ground deeper than the ones that were there before and put in some kind of root barrier to keep plants with extensive root systems from eventually causing all of the supports underneath the entire extension from shifting and potential collapse in an earthquake or in the event of significant soil settlement. The neighborhood nearby had houses that sank and some that heaved upwards because the entire area used to be dairy farms. That one was all slab foundations, but whether the house was on a raised foundation or a slab, the possibility of sink or upheaval was a concern because the prior land use was dairy farming. Add to that, earthquake risks and frequent periods of drought, alternating with el nino weather events? We probably could have used some foundation watering ourselves. :P For the particular concerns about the clay soils where you are and the type of foundation you've got, I'd consider using containers, partial sun/partial shade plants, and hand watering with a hose for the narrow planter area underneath the overhang. The wider one in front of it, something with deeper roots but ones that don't grow like crazy in every direction and more of a ground-cover that is low growing/spreads horizontally more than vertically. I'd suggest going to a plant nursery (if you can find one locally that isn't at a big box chain store like Home Depot, Lowes, etc...that would be ideal) and asking them what they'd suggest, and show them photos taken of the areas you intend to plant in on your phone (since most people have cell phones and those tend to have cameras built into them) for reference.
